roundToDouble method

double roundToDouble()

Returns the integer double value closest to this.

Rounds away from zero when there is no closest integer: (3.5).roundToDouble() == 4 and (-3.5).roundToDouble() == -4.

If this is already an integer valued double, including -0.0, or it is not a finite value, the value is returned unmodified.

For the purpose of rounding, -0.0 is considered to be below 0.0, and -0.0 is therefore considered closer to negative numbers than 0.0. This means that for a value, d in the range -0.5 < d < 0.0, the result is -0.0.

Implementation

double roundToDouble() => value.roundToDouble();
